Eyeray

Eyeray is a term with multiple, unrelated uses, primarily appearing in branding, fiction, and online discourse about vision technology. It is not a formally defined field, and there is no single canonical definition.

In speculative fiction and media, eyeray sometimes refers to a fictional phenomenon involving light interacting with the eye to enable enhanced perception, directed vision, or luminescent abilities. The concept is used to explore themes of perception, consciousness, and the relationship between sight and illumination.

In the consumer technology and eyewear market, "Eyeray" has been used as a brand name for products that incorporate eye-tracking, augmented reality display, or camera-equipped glasses. Variants exist across different companies, with features ranging from gaze-based control to digital overlays for information and communication.

Etymology and usage notes: The term appears to be a portmanteau of "eye" and "ray," intended to evoke optics and illumination. Because it lacks a single standard meaning, context is essential to determine what "eyeray" refers to in any given source.
